This is the first blog post for this year. I prepared a material on the introduction of open source solutions in orchestration and monitoring. This is a fruitful work which constitutes an overview of practical management and monitoring of distributed computational resources. Docker, Kubernetes, and Zabbix platforms were specifically treated. The topology of Kubernetes clusters were depicted. You can access my presentation here.
I came across an excellent educator David Bombal, while trying to learn new things in IT field. I was following his one of labs today. It is a great lab for learning and reinforcing REST API. Main goal of the lab is to practice the API of a Nexus 9000 switch accessible freely by Cisco.
I would like to update some of the content which had been published by David Bombal. Firstly, you should go to the developer website for sign up, and then many resources would be available to you. Amongst them, find "Nexus 9000 AlwaysOn SandBox" lab, and launch it. After launching, new username and password, as well as a host address will be given to you. That address is actually the switch you want to access.
Secondly, authentication payload (the JSON object) a little bit different. Under Section 1. Authenticate of the API, there is a sample payload, and the URL. I used Postman for the request, but I actually prefer curl. The Postman shows the authentication token for the response, which is very cool to see.
